Types ¶

type Controller ¶

type Controller struct {
	// contains filtered or unexported fields
}

func New ¶

func New(
	cmd []string,
	description string,
	controlLogger *log.Logger,
	logger *log.Logger,
	starter func(func(context.Context) error),
) *Controller

func (*Controller) Start ¶

func (s *Controller) Start()

means not necessarily starting a single process, but instead that we'll want to keep this subprocess alive. if it dies, it might get restarted automatically, in which case it gets a new pid, new start time etc.

func (*Controller) Status ¶

func (s *Controller) Status() Status

func (*Controller) Stop ¶

func (s *Controller) Stop()

same goes as for start. stop means that we'll want the subprocess to stop (or "pause"). do not call this when you want to gracefully shut down your app, but instead use the stopper mechanism which will automatically tear things down gracefully

type Status ¶

type Status struct {
	Description string
	Pid         string
	Alive       bool
	Started     time.Time
}
